Breeding songbirds alter their singing behaviour in selectively logged tropical forests


Dr. Rajeev Pillay, formerly a Ph.D. Candidate in Wildlife Ecology and Conservation, is among the biologists worldwide who are concerned about the effects of selective logging on tropical biodiversity.

His research, based on two years of field study in Sabah, focuses on singing behaviour in birds. Birds sing during the breeding season to attract mates and defend their territories from competitors. The song rate of individual male songbirds (i.e. the number of songs produced by a male per unit time) conveys information to females of the same species on the quality of the territory held by a male.

In a study slated for publication this month in the Journal of Applied Ecology, Dr. Pillay and his collaborators from UF’s WEC and the Institute for Tropical Biology and Conservation at Universiti Malaysia Sabah – Robert Fletcher, Kathryn Sieving, Bradley Udell and Henry Bernard – demonstrate that breeding songbirds in Borneo alter their song rates with selective logging.
